Two aeroplanes are departing from an airport. They are flying in a straight line where their flight paths are perpendicular (90 degree) to each other. When the first aeroplane is at 900 km from the airport, its speed is 320 km/hr and it is 2500 km away from the second aeroplane. Find the speed of the second aeroplane at that moment.

The formula in cell C2 is = A$2. Auto fill is used by dragging C2's auto fill box across to D2, E2, and F2. What formulas will appear in D2, E2, and F2, respectively?

Chinara starts with the point (3, 5), and applies the following three-step process, which we call P:Step 1: Reflect the point in the x-axis.Step 2: Translate the resulting point 2 units upwards.Step 3: Reflect the resulting point in the y-axis.As she does this, the point (3, 5) moves to (3, −5), then to (3, −3), and then to (−3, −3).Chinara then starts with a different point S0. She applies the three-step process P to the point S0 and obtains the point S1. She then applies P to S1 to obtain the point S2. She applies P four more times, each time using the previous output of P to be the new input, and eventually obtains the point S6(−7, −1). What are the coordinates of the point S0?
